STEP 3: Press original distributor gear off shaft.
STEP 4:
Mark location of original roll pinhole on the shaft by drawing a vertical line along the shaft that intersects
the hole. Measure from the centerline of the roll pinhole to a fixed point above it. Note that dimension.
STEP 5:
Press new distributor gear onto shaft.
NOTE:
Replacement distributor gear does not have roll pinhole.
STEP 6: Pull distributor shaft out of distributor housing to eliminate endplay (see Fig. 1).
STEP 7: Check location of distributor gear on distributor shaft (see Fig. 1). If it is not in the correct location, use a
press to move the gear to the correct location.
STEP 8:
Using the vertical line on the distributor shaft and the noted dimension (see STEP 4), roughly plot where
the original roll pinhole is located. Drill a new .125" hole 90˚ from the original hole, above or below it,
through the gear and the shaft.
NOTE:
It is important that the dimensions called out in Fig. 1 are maintained while drilling.
STEP 9: Insert roll pin and check dimensions (see Fig. 1).
WARNING:
If the distributor gear is installed incorrectly, it may be forced down against the support in the block or may
be held up away from the support in the block. Both conditions will cause damage to the block and or the
block and gears. When the gear is properly installed, the cut on the gears and the direction of rotation will
pull the distributor gear down against the support (distributor gear thrust face) in the block.

ALTERNATIVE METHOD OF VERIFYING CORRECT DISTRIBUTOR GEAR INSTALLATION:
After STEP 7, install distributor assembly in the block you are using. Timing chain set and camshaft must be removed.
With the aluminum distributor housing fully seated against the block, verify that the distributor gear can be lifted off the
support in the block at least .005". Next pull the distributor gear down against the support in the block and hold it there.
Pull up on the aluminum distributor housing and verify that you can lift it up at least .005" while holding the gear against
the support in the block. This procedure will confirm that the gear is not being forced down against the support and not
being held up off the support in the block.
Continue with STEP 8.
